The aircraft, is I am sure you will know, a Junkers Ju86Z-7, also known as the TP-9. This aircraft, Air Force Serial No 911, was operated by Wing F 1 of the Swedish Air Force at Västerås, but was later transferred to F 7 at Såtenäs.
The original engines were two radial Pratt & Whitney Hornet S-1 E-G of 750 hp each. As these engines proved themselves to be very unreliable, they were changed to Mercury My XXIV engines, I understand the aircraft was written off in 1958.
